AirAid Cold Air Intake w/ Intake Tube for GM Duramax 2004.5-2005 LLY (SynthaFlow)
Cold air is denser than hot air, which means that an engine breathing cold air gets more oxygen than an engine seeing hot air. More oxygen allows for more fuel – that combo means MORE POWER! The quest for cold air is what drives the AIRAID Cold Air Dam Intakes. The CAD Intakes retain the stock filter location but adds a huge air inlet that provides a steady, free-flowing supply of cold air.
This is done via Cold Air Dam panels, which mount in the factory air box location and utilize any factory cold air inlet ducts that are present, while adding additional cold air passages to the filter. These panels also keep the filter isolated from the hot engine compartment air by sealing to the underside of the hood via blade-style weather stripping.
This AIRAID cold air intake is designed specifically for the 2004.5 and 2005 Duramax, and offers a simple, trouble-free installation using simple hand tools. Like the rest of the AIRAID systems, the CAD Intakes are Made in the USA and include all the necessary installation hardware as well as easy-to-understand instructions written with the do-it-yourselfer in mind.
